The concept is good but there are some things i would like to report, first is that you can sometimes also jump in air and you also pass through platforms. and then the collision with the spikes is a bit late so it sometimes doesn't feel that this spike can kill the player. Overall tho the game is good and the art and concept are also very well!

The art and sound is very cool. The concept of having to time the jump well is also cool. When you fall into the void, you have to just reload the page as far as I could tell to maybe add a way to reset the game.

it's really easy to get permanently stuck on things and have to refresh so i gave up really fast unfortunately
nice graphics tho, and the idea itself has potential, good job :]

Within the first 30 second of playing I found 2 different softblocks and had to refresh the page, something I would recommend is adding a restart button to fix this, second I would recommend adding a menu to make the game feel better (this one is more understandable because I didn't have time to add one either) finally I the theme use is good being a platformer, I interpreted it in the same way, but the controls feel to lose, I personally found the middle to be to high and would mainly go for a bit next to it, so to add more measurement/visual I would recommend making the inside like a bar with blue on the outside, green in the middle and red on the inside (and also add the in-between colors so it looks good). It visually feels a little bit plain so I would recommend adding a background and mid background along with some particles, also the music feels a little bit to repetitive, I would recommend making the song longer and adding more structure to the music, the current song feels more like a base rather then the song itself, its like like if megalovania was just the intro again and again, it would drive someone mad, but after that intro repeated 1 or 2 times it goes into the meat of the song and eventually brings that intro back later on.
